| D | checksum-offloads.txt | 26 checksum defined by the sk_buff fields skb->csum_start and
28 checksum (i.e. the 'IP-style' checksum) from csum_start to the end of the
29 packet, and fill in the result at (csum_start + csum_offset).
39 skb->csum_start and skb->csum_offset as described above, and setting
51 which only advertises NETIF_F_IP[V6]_CSUM must still obey the csum_start
82 complement sum from csum_start to the end of the packet will be equal to
85 we simply stop summing when we get to csum_start, then add the complement of
86 the 16-bit word at (csum_start + csum_offset).
